There is a (rare) case where you may need to consider their difference - exit() terminates the current process, no matter where (from which function) it's called. If exit() is called from main() the whole process terminates. - re...

Is there a reason to use exit() over return to terminate a program, or are they equivalent in behaviour?

Someone sent in this question by email The main() function may return (to the operating system) by calling the exit() function, simply calling return, or 'dropping off' the bottom curly bracket. In the last 2 cases, no call to exit() ...

ANONYMOUS wrote When formatting output with printf() and friends, there really is no difference. However when scanning parsing input with scanf() and friends, using " i" supports reading in integers in different numeric bases, such as base-10 (decimal...

I've noticed that both d and i have been used in labs and workshop solutions to print information stored in variables with 'int' datatype. I don't understand when to use which one. Is there a difference between them or can they be used interchangea...

Just "Chris". Glad that you resolved the problem, even if it took such drastic measures. I can't imagine how why you'd be seeing the error you did without it also appearing in so many other situations.

Hi Professor Really appreciated your time to try. just letting you know, I reinstalled xcode and restarted my laptop. copy the code into a new file change the name. it's all good now. really not sure why was that. Thanks again. J

This problem has me stumped. I've tried your code on 2 Apple M2 (Xcode) installations, Ubuntu Linux (gcc), and Redhat Linux (an earlier gcc), and all produced the expected result. I can't imagine why your installation would produce those weird, large v...

Hi Professor thanks for checking with me, as I'm a FIFO engineer, i just back to perth tonight. here's the code for this refresh task. the rest of the tasks are all good, just this first one gave me a funny result. thank you so much for your support. ...

Did you make any progress in solving this problem, Jie?

Just "Chris". I'm afraid that I can't tell from your description alone. It's likely to be the use of an incorrect datatype or a formatting error - not sure. As the exercise is not being assessed, please post your code here.

Hi Sir Experienced weird result for the lab 1 first task (coin change). Run the program in my laptop, enter 75 as purchase value in cents. The result as follow The change is 25 cents. 1 x 20c. 3414288 x 10c. 1 x 5c. 1873589824 x 2c. 1 x 1c. which is not what ...

The webpage https askubuntu.com questions 161652 how-to-change-the-default-font-size-of-xterm gives a simple solution. In your existing xterm, execute prompt echo 'xterm font -fixed- - - -18- ' .Xresources prompt xrdb -merge ...

I'm just getting started with xterm but the font is painfully small, can anyone help me change it?

(I'm afraid) it's working for me this morning; no-one else reported a problem, so hopefully it was just a transient problem.

The link to 'Linux and C compiler basics' seems broken. I cannot access the page. Anyone encountered the same problem? Help appreciated. Thank You.

i followed all the steps, its just when i want the manpages-posix and manpages-posix-dev, my WSL keeps saying "Unable to locate package"

Thanks. I'd presumed that they'd already done that, if (hopefully) following the instructions here https teaching.csse.uwa.edu.au units CITS2002 labsheets software.php But maybe.... The package manpages-posix is correctly named and still exists, https...

try running '''sudo apt-get update sudo apt-get upgrade''' and then running '''sudo apt install man-db manpages-posix''' )

Hello Sir, When running this command "sudo apt install man-db manpages-posix, everything goes well, but then I get an error saying "Unable to locate package manpages-posix"
